Long Term Memory:
•Vast and permanent
•Knowledge of all our experiences, information and strategies
•Developmentally, children and adults always have enough space.
•Controls flow of information
•(strategies, metamemory, etc.) metamemory is knowledge about your memory. For instance saying
you have to write something down because you know it’s the type of information you will not
Does smoking weed have an effect on short or long term memory?
•Depends on whether you do it when you are intoxicated and when you are not.
•THC then binds to receptors, inhibits the release of neurotransmitters around that neuron. So yes
in the short run it does have an effect on your short term memory.
•Interferes with the hippocampus and therefore memory.
Problem with this system:
•Our memory is like a bottleneck. Lots of space but not much can get in at one time.
•How can it work? Memory system comprised of mechanisms and processes which make it
possible. (attention, organization and rich encoding of information, long term memory)
Attention: just focus on what you need to attend to- easy right? Count the number of passes made by the team in
white shirts bounce passes count.
•We only capture what we attend to
•We filter out other available and maybe important information
•Inattentional blindness- failure to notice obvious changes or events
•-staring tight at it but don’t see it.
•Did you see the traffic light?
•Similar filtering/ spotlighting process occurs with auditory information- cocktail party effect.
Levels of Processing:
•How deeply you attend/encode information.
